On 11 September 2020, I gave my inaugural lecture 'Tuberculosis – the never ending story? From Molecular to Global Perspective' as newly appointed "Professor of Infectious Diseases Epidemiology with Special Focus on Molecular Epidemiology" at Global Health Section at University of Copenhagen. If you were not able to participate (COVID), you are welcome to listen to the lecture. About the lecture: In this lecture, I talk about historical and recent perspectives of tuberculosis in Denmark, Scandinavia, Greenland, Europe, and the world - and how it is all connected. At the same time, I explain the concepts of infectious diseases epidemiology and molecular epidemiology. Despite vaccine, diagnostics and efficient inexpensive treatment for decades, tuberculosis remains the leading infectious killer worldwide. Even in Europe, high rates of multi-drug resistant TB in former Soviet Union countries is an imminent concern, and in the Danish Kingdom, Greenland continues to struggle with high rates of TB. At the same time, the welfare state Denmark experiences extraordinary high rates of TB among socially marginalised persons. Tuberculosis is a never ending story.
